The short version

What changed, and why it matters

This update changes how Trezor handles one specific Solana instruction (SetComputeUnitLimit) so it can optionally accept a reference to another program account. Previously the device rejected or could not parse transactions that included this extra account reference, which is used by some services such as Jito. The change is a compatibility fix rather than a clear-cut security patch, but the prior strict parsing could have caused transaction failures or user confusion when signing legitimate Solana transactions.

Recommended action

Treat as a routine compatibility fix. Reviewers should verify that the optional program_ref account is not incorrectly displayed or used in UI confirmation logic, and that the optional account does not affect fee/authority validation. No urgent security action is indicated by the diff alone.

refactor(crypto): change order of parameters

This commit simply reorders the arguments of an internal function called dh() and updates every place that calls it. The actual math and security behavior are unchanged; it is a code cleanup with no security effect.
